Keep reading to learn when and how to use each type of quote effectively.
There is no difference between using single or double quotes, as both represent a string in the end.
The key distinction between using single and double quotation marks is whether you need to use a backslash () to escape the quote character: \’ for single quotes and \” for double quotes.
Use single quotes to escape single quotes and double quotes to escape double quotes.
For instance, a single quote (‘) should be escaped with \\’ within a single-quoted string, while a double quote (“) should be escaped with \\” within a double-quoted string.
However, there is no need to escape the other character inside a string.
So, within a double-quoted string, single quotes can be used without needing to escape them, and the same applies to using double quotes within a single-quoted string.
The choice of quoting style is up to the programmer or developer, and either style has no special semantics over the other.
However, there are some arguments for using single quotes over double quotes:
📌 Single quotes enhances the visual appeal when representing an empty string as ” compared to using double quotes “”.
Here’s an example code that uses both single and double quotes:
let samplestring = "Hi, Welcome to Itsourcecode"; let response = 'Thank you, "I love Itsourcecode"'; console.log(samplestring); // Hi, Welcome to Itsourcecode console.log(response); // Thank you, "I love Itsourcecode"
The code defines two variables, samplestring and response, which are both strings.
The samplestring variable is defined using double quotes and contains the text “Hi, Welcome to Itsourcecode.”
The response variable is defined using single quotes and contains the text ‘Thank you, “I love Itsourcecode.”‘
The code then uses the console.log() function to print the values of these variables to the console.
The first console.log() statement outputs the value of samplestring, which is:
Hi, Welcome to Itsourcecode
The second console.log() statement outputs the value of response, which is:
Thank you, "I love Itsourcecode"
Both types of quotes serve the same purpose of creating string literals, and the decision ultimately depends on personal preference or project conventions.
